All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger. We ask Allaah to exalt his mention as well as that of his family and all his companions.
Imaam Abu Haneefah like all other Muslim scholars among whom are the authors of the six books, were following the Book of Allaah and the Sunnah of the Prophet . All of them endeavour to be in accordance with the Book of Allaah and the Sunnah, and not differ from them. They (the said scholars) did not oblige any person to follow them in every statement of theirs, but rather, they urge the people to follow the Book of Allaah and the Sunnah of His Prophet . We have already issued many Fataawa regarding the ruling of following the four schools, the date of their foundation, etc…, so please refer to these Fataawa: 82358, 87424, 82570and 82778.
Allaah knows best.
